KHACHIMO IPC 400W Power Supply ATX 80 PLUS Gold

400 W ATX Gold power supply for modern standby PCs

This 400 W ATX unit is built for systems that use Modern Standby sleep states and need 80 PLUS Gold efficiency. It suits compact office workstations, home-theatre PCs or light-gaming builds that draw moderate power. Builders who require higher wattage for multi-GPU setups or heavy overclocking should look elsewhere.

400 W continuous output with Gold-rated headroom

The supply delivers up to 400 W across its rails and meets 80 PLUS Gold efficiency targets at typical loads. It handles mainstream CPUs and single mid-range graphics cards comfortably while leaving a small reserve for peak spikes. Sustained loads well above 400 W will exceed its rating and trip protection.

Zero RPM fan mode and LLC topology for quiet

A resonant LLC design with DC-to-DC conversion keeps voltage regulation tight and reduces coil whine. At low and medium loads the fan stops completely, giving near-silent operation during idle or media playback. Under heavier load the fan spins up to maintain safe temperatures without excessive noise.
